The names of Alex Song and Theo Walcott have been added to Arsenal's injury list after both picked up knocks during the 2-1 win over Everton on Tuesday night.

Song was replaced by Abou Diaby at half time and although Walcott completed the game he was nursing an ankle problem after the final whistle.

"Song cannot walk," said Arsène Wenger during his post-match press conference. "I don’t know what he has got.

"He was kicked, I think it was by Koscielny, he knocks out everybody in our team! So we have to see how he responds to that in the next days, but he cannot walk at the moment."

The Arsenal boss also gave an update on Samir Nasri's fitness after the French star limped out of Sunday's FA Cup win over Huddersfield.

"For Nasri, the scan shows a hamstring strain. [He will be out for] 21 days," reported Wenger.
